• The main results are : supersonic region and subsonic region can co - exist in flow path simultaneously , subsonic flow is insignificance for engine performance ; total pressure of primary rocket should be decreased when mach number is increased . in the experimental aspect , some components of ejectorjet experimental system were improved , ejectorjet experiments using alcohol as secondary fuel were conducted
  由数值计算获得的结论为：引射火箭内的一般流态为超音速区与亚音速区共存，亚音速区不具备做功能力；飞行马赫数增大，引射火箭内更易于产生壅塞；为了获得最佳的性能，随着飞行马赫数的提高，应当降低一次火箭的工作压强。
